Tests on an airplane model, AEG D I of the Allgemeine Elektricitats Gesellschft, A-G, airplane construction section conducted at the Gottingen Model Testing Laboratory for Aerodynamics
A 1923 NASA technical report compiling wind-tunnel test results for a model of the AEG D I airplane, made by the Gottingen Model Testing Laboratory for Aerodynamics for aircraft designers and engineers. Its pictures are engineering charts of lift, drag, aileron and elevator settings, with plotted curves and data points on plain grids, showing how a designer might read performance trade-offs from graphs.
